To all whom it may concern.- I

Be it known that l, CLARENCE H. HOWARD, a citizen of the United States,residing at St. Louis, in the State of Missouri, have invented a new anduseful Improvement in Locomotive Pilotdleams, of which the following isa specification.

My invention relates to a locomotive end-sill or pilot-- beam, and is inthe nature of an improvement on the letters Patent granted to Westlakeand Thomas, February 19, 1907, number 844,765, for an improvement inlocomotive engine frames, in which the endsill is formed with arcarwardly projecting bracket be tween the longitudinal beams of theengine frame, combined with webs depending from the said sill andbracket and forming therewith a housing for draft- My invention has forits object, to dispense with the separately constructed (onplcnpockct'and its braces ordinarily attached to the front side of the end-sillfoia short shank coupler, also to enable an ordinary couplcr to be used (oroverhanging the pilot sullicicntly to prevent interference therewithwhen coupling the engine to a car or other rolling stock, and toincrease the strength and rigidity of the end-sill or pilot-beam.

The invention consists in features of novelty as lit-rcinaiter describedand claimed reference bcing had to the accompanying drawing forming partof this specification, whercon,

Figure l, is a top plan View of a mcfcmble form of my improvedlocomotive cud-sill or pilotdn-zun; Figs. 2 and 3, a front and cudelevation thcrcof respectively, and Fig. l, a vertical longitudinalsection through the cndill on line s 4, in Fig. it

Like letters and numerals of reference denote like parts in all thefigures.

a represents my improved cud-sill or pilot-beam, which excepting theparts thereof forming my invention, is preferably, substantially similarto the end-sill described in the said patient, having its luuly-portir u1, preferably box-shaped in cross section, with its top and bottom wallsparallel, but, in the prcscnt (115v intotsectt-d inmsrcrscly at themiddle for a suitable distance from the top Wall by a box-shaped portion2 of reduced depth, which forms a space thercat beneath the bottom ofthe portion 2 and that of the divided parts of the main body-portion l,the box-shaped portion 2 projcctirw for a suitable distance from thefront side of the body-portion l aud forming a dcad-blocl to thecud-sill a, thrwhole with its combined adjuncts as hereinafter referredto, being composed preferably, of cast steel integral throughout; butthe body-portion 1 may be of any other suitable shape in cross section,such as channel, longitudinally at the top and bottom as shown, or

I, or T-shsped, and either straight otherwise, and with or without thereduced middle 5 portion 2 as desired. The end-sill a is adapted to hearat. its rear side against the ends of [llO longitudinal 1ne 'tallicbeams Z: of the engine frame, as indicated by dotted lines, and in thepresent case is formed on its rear side between the beams b, with abracket c adapted ,to bear laterally against the inner fact-s ofthebeams b to which it is firmly fixed, and having an opening 3therethrough for the upright center or pivot-post (not shown) of thepcny-truck of the engine frame, Furthermore, from the underside of theend-sill a and bracket 0 depend two opposite and parallel upright- Wcbs4 (one on each side oi the longitudinal centroi the engine frame) havingupright lug or stops l and otherwise adaptcdon their inside faces toform a pocket. or housing for a suitable coupler (and ctaubined draft--gear) as indicated by dotted lines inll ig. all the said partsheretofore recited being nracticelly the -12 the corresponding parts setforth in the said patent, a :d therefore, needing no furtherdescription.

Projecting from the front side of the body-portion 1, preferably at thetop or adjacent thereto for its entire length, or thcrcnbout, andintegral therewith, is overhanging member ll, comprising preferably, ahori zontal web (5 which in the present case forms at, its middle part;the top wall of the forwardly projecting box-shaped portion 2 of thebody-portion l, and thence prcfcrably inclines rearward to each end ofthe bony portion 1, the outer edge of the web 6 having preferably adcpcnding ilnnge 6 which forms at the middle in the present. case thefront end wall of the box ,QBLi portion 2, and thence suitablyconfigured inclined downward to each end of thebody-portion 1 at thebottom, the whole forming a strong rc-inforcing com" prcssion member tothe cud-sill a and increasing its rigidity and resistance to violentfrontal shocks. 'lhrough the web (5 are preferably lightening holes 7,7, Or the ovm'hangiug member at in front of the sill a may beothcrwisc-configured as ionud most suitable. By this CtniStllH'tiOllalso, the projecting box shaped portion 2 of the body-prwtion .l isstrengthened and ('nztblod to be extended outward from the bodyportion isuriiriontly to permit of using an ordinrry coupler in iltll of theshort shank coupler with its separately constructed pocket fixed to thesill and later-all} braced thereto, and thereby enables the engine to.h' coupled to a car or othcr rolling stock without interfering with thepilot (not, shown) which in the prosen' .ztso is fixed to the front sidewall of the body-portior hand tobmckcts 8 depending therefrom.

in cases where the projecting box-shaped portion of the body-portion 1is eliminated, the overhanging member d may be suitably shaped and orurged a: its middle portion to form a dead-block to the sill, and

if required adapted 011 its under portion to form a suitably shapedcoupler-pocket and brace integral with, 10 pocket Orhousing for adrafvgem according to various and overhanging the front side of the saidbody at the yp of 9nd sln or pilot beam top, or adjacent thereto, forits entire length, or thereabout. substantially as described. I make noClaim to torwayd cxtenslon of the in testimony whereof I have signed myname to this 5 8111 at the middle t0 form 2, dead-block thereto butspecification in the presence of two subscribing witnussosi 15 CLARENCEll.
